As far as I know, It is impossible to keep all the features when the model is transferred from CATIA to UG, or from UG to CATIA.
From the view of point of engineering, the interface of data exchange in those large CAD/CAM softwares is not as good as we expect. Generally, the geometric shape of solid model could be hept. However, this condition, sometimes, doesn't happen to the surface, especially to complex surface model.
Good luck to you. |
